synaptics - tap&click issue

Hellorecently installed arch on my HP nc8430 with synaptics touchpad.Having this extremely annoying issue with tap/click feature. Very often when i tap the touchpad in order to click something, it doesn't get registered.It's like the options for synaptics aren't set well. But they are!i tried to use gsynaptics, synclient to tune the settings but whatever i do nothing does improove the issue.
